Abstract：Thisstudyselectedaseriesofnanocellose products，includingcellose nanofiber（CNF），cellosenanocrystal（CNC）， andbacterialnanocellulose（BC），forthepurposeofpreparing tobaccohumectants.Aninvestigationwasconductedintothespraying parametersandtechnicalaproaches.Subsequently，thefectsofdiferentnanocellosetypsotobaccohumectancy，flavoren hancement，chemicalstructure，surface wetability，microstructure，andspecificsurfacearea wereevaluated.Theexperimentalfindings demonstrated that the water retention values of the nanocelluloses ranged from 93% to 99 % ， with interfacial wetting angles ranging from 6.6∘ to 22.2∘ . When CNF with a carboxyl group content of 2.5mmol/g was sprayed onto the tobacco surface at a loading of 2.0% ， the tobacco experienced a moisture loss rate of 49% ，which was comparable to the propylene glycol. Besides，the decomposition productsofCNF-basedhumectantsduringtobaccocombustionhadbeenshowntoprimarilyconsistofalkanes，heterocyclics，aromatics，furans，aldehydes，alcohols，sters，andcids.Teincorporationof teseC-basedumectantsdidnotmodifytedisrbutioofto baccodecompositionproductsorthesensorycharacteristicsoftobacosmokeatheritenhancedthesnsoryhumectancytoertain extent.Structure-activityrelationshipanalysisrevealedthatCNF-basedhumectantsprimarilyachievedtheirmoisturizingeffect through a synergistic effect of hydrogen bonding and surface sealing effect.
